Dependences of the Si:Bi laser emission on the pump macropulse energy when pumped in the vicinity of the bismuth state (pump frequency ) and in the conduction band bottom . A sketch of the experiment geometry is shown in the upper left corner.
Typical pump (FELIX) and Si laser emission pulses. The gates used for measurements of the time-resolved pump spectra in Fig. 3, are shown. The lower trace is exaggerated by a factor of 5.
(a) Spectral dependence of the pump radiation transmitted through the Si:Bi sample. The inset shows the positions of bismuth impurity lines. (b) Emission from the Si:Bi laser as a function of pump frequency. The two curves correspond to signals registered with the gates shown in Fig. 2.
Typical emission spectra from the Si:Bi laser for different pump wavelengths . The inset shows the Raman laser scheme. The upward arrow represents the pumping and the downward arrow represents the laser emission.
